US Cold, the nation’s premier provider of refrigerated warehousing and logistics, announced results from a groundbreaking pilot project with Rypos, a leader in diesel particulate filter (DPF) technology. The project demonstrated a nearly 90% reduction in emissions from refrigerated trailers, reinforcing USCS’s commitment to being the industry’s Best in Cold when it comes to people, logistics, and facilities. Over a 75-day test, four refrigerated trailers (TRUs) were retrofitted with Rypos DPFs, while four trailers served as controls. Using EPA-approved methodology, USCS measured particulate matter (PM), total hydrocarbons (THC), and carbon monoxide (CO) emissions and converted them into carbon dioxide equivalents (CO₂e).
